TURBINE.

` Application iled March 16,

compressing` the flui o avol ute case, within wh rotor is provided,lsaid laminatio The invention is illustrated bv ample in t which: i

Figure 1 is a viewin central longitudinal section through the structure.

ig. 2 is a view in central transverse section through the turbinedisclosing tion ofthe volute oase'to i l Referring more particularly tothe drawings, 10 indicates a volute This struc` ture is substantiallycircular, having an ine uction nozzle `11, and eduction passageways 2and 13. By referring to'F" way'ofexhe accompanying drawings, in

of te case. v a and 13 cominunithe conoidal case cuinferential portionof i `case is which is a continuation arranged induction nozzle 11 andsageway decreases in sectional area as it Y Y within the case with itscentral transverse plane with the transverse `center of the conoidalcase.

The rotor is mounted upon a i shaft19"disposed. eccentrically of thevolute f of greater section than the reinainin `at eith is formed withwhich is beveled Huid to produce r The present inventioncontemplates-the use f 'ch a laminated ns bein@ `to insure that a`motive fluid will be made throughout the the fluid may take place asits tion openings 25 openings as shown in :increasing area toward 16 andinto the eduction i will b axis in the saine 1921. Serial No. l52,650.

d receive e rotor itself is formed with a plurality of laminated disks.large turbines the central er side and which a throat 22, establishingcommunication between th Whichwill thereafter encounter the surfaces ofother rotor disks.

n t e present instance three other sets of disks are shown as indicatedat 23, 24 and hese disks are all formed with double fe edges and arearranged and designed uniform distribution of the kni rotor and that)ended and. as the fluid i travels toward educin each of the disks.These Fig. 1 are of graduallyr rotors and are the fluid pacing washers27 tween the various plates and form the hub ofthe rotor. These washersand the plates `are secured together bv fasteners such as rivets 28 aridare hired to the rotor shaft 19. In 1 th so that the Slightly used as agenerator a fluid is delivered to the nozzle 'll under high pressure andvelocity. rl`his nozzle is tangent to the circumference ot the volutecase and will direct the tluid into the volute passageway 17 which`gradually decreases in its sectional area. This arrangement will causethe gases to pass through the annular throat 22 leadingfrom thepassageway 17 to the main chamber of the casel it is divided intovarious streams which .pass between the laminations of the rotor. t isintended that the laminations arranged as tc equally divide oi' `fluidpassing therebetween. but it this does not lexactly occ-ur7V equilibriummay be established by the passage ot fluid through slots Q9 in thedisks. rlfhese slots are 'formed with substantially radial lrnite'edgeswhich will oiler slight Vresistance to the fluid as it `passes throughthe dislr. Eis-shown' in the drawings, sets ot these slots' are arrangedin alignment along diilerent. circles yon the disks. The passage of thefluid between the glates will cause a rotation ofthe rotorin vthedirection ot travel of the fluid which. rotation will be imparted to theshalt 19. The ll'uid may then pass 'from thecase through the eductionpassageways l2 and lf3. lf the vturbine is to be used as apump or aconipressor the rotor 19 is driven at ot' speed, and will act to impartmotion to a fluid drawn in the rase, which fluid will be yenpelledthrough the tangential nozzle vl1.

lt'will thus be seen that the turbine here disclosed, while otsiinpleconstruction, yet provides eilect'ii'e means tor obtaining power from amotive luidor tor imparting motion to a liuid.

While ll have the volumes shown the prei'erred torni ol. my invention asnow known to me it wil be understood that if'arious changes might bemade in,the combinationa` construction and arrangement otl parts bytho-se skilled in the art, without departing` from the spirit of theinvention` asclaimed.`
